Harrow — Silent Mass

Endgame build. Roar or Eclipse over Penance. Covenant is still the crit window. Condemn still prints shields. You are a headshot platform with a priest costume.

Codex Checked · Compared against current game data for this update. · Update 43.5 · 5 Sept 2026 · PC · Current

Incarnon snipers, Kuva / Tenet crit weapons, people who skip Penance

Wrong drop or mechanic?

Don’t build this yet

First Sermon first

This loadout sits at Endgame. It wants Forma, Helminth, or shards you may not have. Play the Starter until those systems are open — then this page is the upgrade, not the homework.

Open First Sermon

Why this build?

Endgame for Incarnon snipers, Kuva / Tenet crit weapons, people who skip Penance

Health: Not yet — Helminth, Steel Path, or Archon Hunts still closed. Play the Starter.

Play this in Steel Path
  • Not every Harrow wants Penance. This is the 'I brought a sniper' loadout.
  • Helminth 2, not 4. If you drop Covenant you dropped Harrow.
  • Lasting Covenant still wants headshots. Body-shot beams are a different priest.

Don’t use this for: ability-nuke as the damage · players without Helminth

Specialised investment for hard content

You don’t need the shards to run the loop. They are a later ceiling, not a gate.

Bring: The actual crit gun — Headshot weapon. Lasting Covenant plus Roar plus Avenger is the multiplier. Condemn holds them still.

Readiness

Inventory unknown

Not checked — add your collection. You have not failed a test.

  • Required mods 0/9 · required — 0/9 named
  • Forma 0/4 · required — 4 on the card. Codex does not track installed Forma.
  • Helminth 0/1 · required — Subsume Roar (Rhino) or Eclipse (Mirage)
  • Arcanes · recommended — 0/2 recommended
  • Shards · optional — Optional unless the card says a breakpoint

Investment: 4 Forma · Reactor · Helminth (Roar (Rhino) or Eclipse (Mirage)) · 2 shards · 4 specialised mods. Typical farm ~4–6 hours. Trade if a route is vaulted.

Codex Checked · Compared against current game data for this update. · Update 43.5 · 5 Sept 2026 · PC · Current

Medium confidence. A solid recommendation with more situational dependencies. Confidence is not verification. Verification is separate: Codex Checked against Update 43.5.

Farm the gap

Helminth & shards

What to put on the body

Roar (Rhino) or Eclipse (Mirage) over Penance (2)

Penance is fire rate and lifesteal. Redline-tier guns already have fire rate. Roar/Eclipse is more damage. Keep Covenant. Keep Condemn. Keep Thurible.

Helminth is locked. Tick it on Progress before you subsume.

Tonight

What is actually up

30 minutes, one hour, or two — matched to this loadout, not a dump of the Origin System.

  1. 30 minutes

    Farm Growing Power

    One named gap. The Silver Grove quest

  2. 60 minutes

    Growing Power, then Forma

    Finish the missing named card, then spend a Forma if a polarity is still fighting you.

  3. 120 minutes

    Subsume Roar (Rhino) or Eclipse (Mirage)

    If you are logging off after this, stop at the named component. Do not start a second Forma session tired.

Who this is for

Play this build from zero

You brought a sniper and Penance feels like a wasted button.

Mass loop

Pocket card. Stick this on a second screen; the long version is the mission below.

  1. 1Condemn (1). Covenant (4) in the open. Roar or Eclipse (2).
  2. 2Headshot. Lasting extends 4. Recast Roar as needed.
  3. 3Thurible (3) if you or the squad dipped. You still print energy.
  4. 4Do not skip the Covenant peek. Tiny absorbed damage is a tiny crit buff.

First mission — press these buttons

  1. 1

    Condemn, Covenant peek, Roar, shoot heads

    4

    The window should not drop if you can aim.

  2. 2

    Do not skip the peek

    Roar does not replace absorbed damage. 4 still needs to eat shots.

Common mistakes

  • Helminthing Covenant

    Then you are a Roar stick with chains. Put it on 2.
